Be it known that i, JOUANN Fiifesoims, citizen oi Hie Republic of Switzerland, tosiding Ninterthur, Cmiion of Zurich Switzerland, have invented the ioiiowiiigdescribed improvements in 'Water-Cooieci Internalfiombustion Engines.

The invention relates to internal combustion engines, and more particularly to the water-cooling provisions thereof. When the Water cii'euleteci through the Water-jackets of these eii ines contains lime scale s surfaces, mifl, being a p iosmeci on me conductor oi heat, pro ""138 proper coomig heating of ins parts so coni-eci and H? meet oi the Working and Wearing qua of the engine. The ob ieet of the present in C i .L
